Empirical Formularization of Sealing Performance of Rubber Valves Used in Automobiles

Many control valves utilizing the vacuum pressur of engines are used to control the engine, fuel supply, and driving speed.

The authors established an empirical formula regarding sealing performance of control valves made of rubber.

This formula clarifies the relationship amoung the rubber valve design factors, the counter surface conditions, and the vacuum conditions, with the sealing performance.

By applying this formula, it became possible to predict the sealing performance of control valves at a design stage to satisfy the customer's specification.
